But... but... but... Bill Polian is a Super Genius, who has never had a bad draft! Right?
And no, I am not denying his success. This is just to remind all of us that most "dynasties" are teams that managed to gather a good group of players in a concentrated period of time (itself a product of good drafting, judicious spending, and a generous dollop of good luck), seasoned with a few felicitous choices of role players. The very existence of great players on the team makes it difficult to select their replacements until they are about done, which is why so many "dynasties" (a term I do not like, for another conversation) suffer down periods after those core great players leave the scene.
